Abstract

L'invention concerne un procédé de codage d'hologrammes produits par ordinateur dans des modulateurs de lumière pixelisés, dont la surface de codage présente une matrice de pixels pourvus d'une forme et d'une transparence. La surface de codage contient un hologramme (12) composé de sous-hologrammes (201, 211), un point d'objet (30, 31) de l'objet (10) à reconstruire avec l'hologramme (12) étant affecté à l'hologramme. L'invention vise à empêcher essentiellement la falsification de la reconstruction de l'hologramme due à la forme et à la transparence des pixels, et à réduire le temps de calcul pour la correction de l'hologramme. A cet effet, chaque sous-hologramme individuel (201, 211) produit par ordinateur est multiplié par une fonction de correction (K) et ce n'est qu'alors que les sous-hologrammes corrigés (201, 211) sont additionnés pour former un hologramme global (12), la fonction de correction (K) employée étant une projection des réciproques des transformées de la fonction de pixel sur le plan d'hologramme, affectées à la fenêtre d'observateur virtuelle (11).
